HOWARD M. DUDLEY, OF PHILADELPHIA, PENNSYLVANIA.

DYEING-MACHINE.

Application filed* .T une 30, 1917. Serial No. 177,954.

To all whom t may concern:

Be it known that I, HOWARD M. DUDLEY, a citizen of the United States, and a resident of Philadelphia, in the county fof Philadelphia and State of Pennsylvania, have 1nvented certain new and useful Improvements in Dyeing-Machines, of which the following is a specification.

My invention relates to dyeing machines and refers particularly to machines suitable for the dyeing of silk in the form of hanks, hosiery, etc., by means of a circulating dye liquor.

One object of my invention is a device whereby textile fibers may be dyed evenly Ywithout manual manipulation.

Another object of my invention is a device in which a dye liquor may be passed in opposite directions through textile iibers.

Another object of my inventon is a device in which those portions of the fiber which rest upon the supporting bars are dyed evenly with other` portions of the fiber.

Another object of my invention is a de vice in which the dye liquor is distributed evenly throughout the dyeing chambers.

Another object of my invention is a testing device whereby the condition of the fiber in the dyeing chamber may be determined without opening the dyeing chamber or disturbing the liber'therein.

These and other objects of my invention will be evident upon a considerationy of my speoiication, drawings and claims.

In the dyeing of fibers and fabrics it is necessary that they be moved continuously through the dye liquor or that the dye liquor be passed continuously through them in order that all portions may receive equal treatment to produce even dyeings.

My device overcomes all of the above and other dificulties and presents a method whereby uniform and even dyeing results may be obtained with a minimum of time, labor and expense.

In the accompanying drawings, illustrating modications of my device, similar parts `are designated by similar numerals.

Figure 1 is a vertical cross-section of one form ,of my device.

Fig. 2 is a cross-section through the line Specification of Letters Patent.

Fig. 3 is a top plan view showing the top in a revolved position. Y

Fig. 4 is a cross-section through'the line 4 4 of Fig. 1.

Fig. 5 is a top plan view of a portion of one of the foraminous plates.Y

Patented July e, 191s.

Fig. 6 is a broken cross-section 'through the line 6 6 of Fig. 5. l Y

Fig. 7 is a broken cross-section through the line 7 7 of Fig. 6. l

j Fig. 8 is a cross-section of a modification of the top and bottom members.

Fig. 9 is a cross-section through the lines 9-9 of Fig. 8.

The form of my device as illustrated comprises a dyeing chamber` formed by the side members 10, 11, 12 and 13, abutting upon "the members 14, 14, 14, 14, which extend somewhat inwardly from the side members producing a supporting ledge 15, 15 for the purposes explained later. A smaller testing device 16 is adjacent tothe side 10, and connected to the lower portion of the dyeing chamber by the conduit 17 and to the Vupper portion of the dyeing chamber by the conduit 18. The space 19 in the lower Vportion of the dyeing chamber is connected by the pipe 20, having thevalve 21, with'the pipe 22 which in turn is connected with the pipe 23. The pipe 23 is connected by means of the pipe 24 with the discharging side of the pump 25. The receiving side of the pump 25 is connected with the pipe 26, having the valve 27, the pipe 26 being connected with the lower part of the reserve tank 28.y The pipe 26 is also connected with the pipe'29,

by means of the universal joint 31 with the pipe 32 having the valve 33. The pipe 32 leads into the chamber 63 formed by the top member 34, capable of being clamped to the side member by the Vclamps 35, 35.4 A pipe 36, having the valve 37, leads Vfrom the up.- per portion of the dyeing chamber to the top of the reserve tank 28. A pipe-38, having the valve 39 connects the lower portion of the dyeing chamber with the pipe 36.

The pipe 40, having the valve 41, connects the pump 25 with a source of water supply. Within the dyeing chamber are a seriesof of which is comprised of the foraminous bottom 43, the imperforate sides 44. 44, and the exterior supporting members 45. 45 which are capable of slidable engagement within the indents 46. 46 of the side walls of the dyeing chamber. The upper Y,portion of each supporting member 45, 45 is partially cut away and pins 47. 47 inserted .to engage with the hooks 48. 48 whereby the berchambers may be vremoved from lwithin the dyeing chamber.

A foraminous top plate 49 is .capableo'f abutment upon the top of the ber chamber 42B. Y

Within the testing chamber 16, a testing '-berfchamber 50 similar tothe ber chambers 4 2, 42A. 42B is capable of being supported .by the lugs l51, `51, and a foraminous top plate 52 placed thereon.

` The foraminous plates 43, 43. 49 consist of a series of parallel members comprising upwardly and' downwardly (divergent `.members 53. 53, having the openings 54. 54.

Figs. '18and 9 'illustratea modification of the upper and-lower members of the dyeing chamber,fcomprising the shell within which are the upwardly and downwardly extended 1n'embers`55. 55 havingthe'openings 56. 56. 'The Aoperation of 'the device is as follows, assuming that the 1ber chambers are removed. 'Each of the ber chambers 42, 42A, 42B is :packed with 'the `ber or fabric to be treated and placed within the dyeing chamber as shown in Fig. 1, the Atop foraminous plate 49 =being placed upon the upper ber .chamber. The top l34, which is in the position-shown by the dotted lines 34A of -F ig. 3, is Lrevolved upon the .universal 'joint 31 un- Ltil A'it -is yover the tops .of the side members yoi the ,dyeing chamber and is then clamped thereto "by means of the clamps 35. All zof the val-ves are closed with the exception of valves l'30,121 and 37 and the pump 25 -='is lstarted'. The liquor passes from the dissolving tankfnot shown, through the pipes *'29, the pump25, the .pipes 24, 22 and 20. the

chamber 19, :the fber chambers 42, 42A, 42B, and the pipe 36 into the reserve tank 28. When sufficient dye liquor has been brought finto circulation, all the valves are vclosed with the exception Iof valves 21,37 and 27.

"The liquor know ,passes vin continuous circullation `from the pump 25 Vthrough the pipes 22, l'20, chamber 19, ber chambers 42. 42A. y4213,pipe 36, reserve tank/28 and pipe 26 back .to the pump 25. During this operation, the liquor also passes through the conduit 17., the ber ,chamber 50V and the conduit 18 into Ithe chamber 63. `When this circulation :has been continued for a sufficient length ofi time, all the valves are closed with thepexce'ption of valves 33, 39 and 27 The .liquor now passes in a reverse direction ,from .the pump 25 through .the Vpipe y32, chamberV '63,v ber chambers 42B. 42A. 42,

pipes 38, reserve tank 28 and pipe 26 back to the pump 25. During this operation, the liquor also passes through the conduit 18, the ber chamber 50 and the conduit 17 into the vchamber 19.

Fresh water may be passed through the ber chambers "by means of the pump 25, by Y`opening the valve 41 and closing off the dye lliquor supply.

I .do y not limit myself to the particular size, number, shape, or arrangement of pants, Ias-.showai and described, all of which may be varied without going beyond the scope of my invention -as described Iand claimed.
